Abstract (en)

[origin: EP1246323A2] A tunable optical oscillator that generates optical signals at a band of micro-to millimeter-wave is provided. The tunable optical oscillator (10) includes an electrical signal generator for generating an electrical signal at the predetermined band; a master laser that is driven by the electrical signal, and generates an optical signal having a first frequency; and a slave laser that is driven by an electrical signal, injected into the optical signal generated by the master laser, generates an optical signal having a second frequency, and mixes the received optical signal with the optical signal having a second frequency to be output. The tunable optical oscillator is capable of generating signals over a broadband including micro-to millimeter-wave and beyond, say, from tens of MHz to several THz. The generated signals by the optical oscillator have also frequency tunability over the range of tens of GHz with coarse tuning methods to tens of MHz with fine tuning methods. <IMAGE>
